Abstract

The utility model relates to an elevator sedan -chair frame fast -assembling nut plate, including being used for installing the square board in the limit is bent to sedan -chair frame stand, the bend width unanimity of width with the square board in the U type groove that the limit formed of sedan -chair frame stand, it has four screw holes to follow the length direction equipartition on the square board, and screw hole one end edge extends along screw hole central axis direction has annular bulge. The utility model discloses a nut plate adopts a square board to make, square board can block the U type inslot in the hem formation of stand, tighten the bolts current prescription shaped plate has the anti -inversion function, the rotation takes place for nut plate in the time of can preventing fastening bolt like this, only need twist the commentaries on classics bolt during installation need not with spanner chucking nut, only need firmly can with the have gentle hands flicking, so that the operation is convenient, time saving and labor saving, the installation effectiveness improves at double, in the time of can obviously shortening the erector of elevator, reduce the installation labour cost of elevator.

Description

A kind of elevator car frame Fast assembling nut plate

Technical field

This utility model relates to elevators field, is specifically related to a kind of elevator car frame Fast assembling nut plate.

Background technology

Along with the rise day by day of the most domestic human resources's price, human resources in the cost of plant equipment The proportion occupied rises the most day by day, and therefore idea manages to reduce the cost raising work that manpower factor is occupied Efficiency, significant to the economic benefit of an enterprise.The upper and lower beam of traditional elevator car frame and When column junction is with bolts, many employings bolt adds flat, the mode of spring washer, hex nut, fixing Time for preventing nut rotation, nut need to be blocked with a hands spanner, an other hands screws up with a wrench spiral shell Bolt, realizes fastening.Owing to during elevator assembly sedan-chair frame, elevator main guide rail has been mounted to position, main guide rail Work surface is in the centre position of column and the least with column gap, so installing space is the narrowest and small, and institute During to use traditional fixed form, operation is inconvenient for and wastes time and energy.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of elevator car frame Fast assembling nut plate, and it is installed Time only need to twist bolt without with spanner card jack panel, very convenient to use, installation work-hour drops significantly Low.

For achieving the above object, the technical scheme that this utility model is taked is:

A kind of elevator car frame Fast assembling nut plate, including the square plate in being arranged on sedan-chair erection post bending edges, The width that sedan-chair erects the U-type groove that post bending edges is formed is consistent with the width of square plate, edge on described square plate Length direction is evenly equipped with four screwed holes, and screwed hole one end margin threadingly hole central axis direction is extended with ring Shape is protruding.

The thickness of described square plate is 6mm.

Nutplate of the present utility model uses a square plate to make, and square plate can be stuck in the flanging shape of column In the U-type groove become, when tighting a bolt, square plate has anti-reverse function, is so possible to prevent fastening bolt Time nutplate generation rotation, only need to twist bolt during installation without with spanner card jack panel, only need to be light with hands Flicking is lived, and operates very convenient, and time saving and energy saving, installation effectiveness significantly improves, and can substantially contract The installation work-hour of short elevator, reduces the installation labour cost of elevator.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model embodiment；

Fig. 2 is perspective view of the present utility model；

Fig. 3 is that this utility model assembles structural representation.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, a kind of elevator car frame Fast assembling nut plate, including for being arranged on sedan-chair erection post Square plate 4 in the bending edges 7 of 1, sedan-chair erects post bending edges 7 and constitutes a U-type groove, the width of square plate 4 Spending consistent with U-type groove width, such square plate 4 is just stuck in U-type groove, square plate 4 when tighting a bolt There is anti-reverse function, square plate 4 is evenly equipped with four screwed holes 5, screwed hole 5 one end along its length Edge threadingly hole central axis direction is extended with annular projection 6.The thickness of square plate is 6mm, it is ensured that square Plate has some strength.

As it is shown on figure 3, it is used for car frame underbeam and the assembling schematic diagram of column for nutplate, column 1 is one Individual for C-type steel bending part, two bending edges of column both sides respectively constitute a U-shaped draw-in groove, Qi Zhongyi The circular hole wearing bolt it is machined with on individual bending edges；Underbeam 2 and column 1 junction are welded with two angle bar, The circular hole wearing bolt it is machined with on angle bar；Nutplate is the rectangular steel plates that one piece of 6mm is thick, at this block rectangle Have on steel plate four by the columnar projections of circular hole in piercing and flanging processes out four band, four The Surface Machining of interior circular hole has screw thread.First column 1 is inserted between two angle bar of underbeam 2 time assembled, After insertion, the circular hole on alignment post 1 and underbeam 2, then snaps in nutplate in U-shaped draw-in groove so that The screwed hole alignment post 1 in nutplate and the circular hole of underbeam 2, then in the outside of underbeam 2 angle bar Penetrating bolt 3, bolt 3 is tightened in the screwed hole of nutplate after the circular hole on column 1 and underbeam 2. The upper beam of sedan-chair frame and the connection of column are similar with the connected mode between underbeam and column, and whole sedan-chair frame is assembled The traditional hex nut of Shi Buyong picture installs one by one, tightens one by one, and installation effectiveness significantly improves.

Claims

1. an elevator car frame Fast assembling nut plate, it is characterised in that: include for being arranged on sedan-chair erection post bending edges Interior square plate, the width that sedan-chair erects the U-type groove that post bending edges is formed is consistent with the width of square plate, institute State and on square plate, be evenly equipped with four screwed holes along its length, screwed hole one end margin threadingly hole central shaft Direction is extended with annular projection.

Elevator car frame Fast assembling nut plate the most according to claim 1, it is characterised in that: described square plate Thickness is 6mm.
